SPECIFICATION forming'part of Letters Patent No. 593,006, dated November 2, 1897.

pplicationrled April 13, 1897.

To @ZZ whom it may concern.-

Be it known th at l, JACOB XV. VVOLFE, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented a new and useful Grate, of which the following is a specification.`

This invention relates to that'class of heat-r ers arranged in a space or iireplaceprovided in a division-wall of a house or dwelling'and utilized for heating either or both rooms or apartments separated by the said wall, the heater being movable to one side or the other or to an intermediate point of the divisionwall, according as the heat is to be thrown into one or the other of the rooms or into both.

The grate is mounted upon rollers, so as to be readily shifted, and is composed of halves or parts, each having independentconneetion with a base, and combined therewith is a pivoted cowl and a vertical diaphragm, the latter being located within the cowl so as to control the draft and heat, whereby when the grate is withdrawn from the fireplace into one or the other of the rooms" the vertical diaphragm will swing back against the cowl on the other side and form a back wall for the purpose of throwing ont the heat into the room. having the heater drawn therein.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description. Y

The improvement is susceptible of various changes in the form, proportion, andthe mi nor details of construction without depart`- ing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure lis a perspective view of the improved heater, showing it drawn into the vnear room. Fig. 2 is a vertical section showing the heater intermediate of the rooms.

Corresponding and like parts are referred to in the following description and indicated in both views of the accompanying drawings by the same reference-characters.

The partition or division wall l separating the rooms or apartments to loe heated is provided with a replace or space 2, in which is Serial No. 632,038. (No model.)

located the improved heater, consisting of a base 3, mounted upon rollers or wheels 4,

g'rates or 'lire-baskets 5, secured between the sides of the base, a pivoted cowl 6, and a vertical diaphragm 7, the latter being located 'within the cowl and supported so as to swing freely, thereby adapting itself to the relative location ofthe parts, whereby the smoke and gases are properly directed through the flue or chimney provided in the wall l.

The sides of the base slope upwardly from their edges, forming extensions S midway of their edges, which project into the lower end of the pivoted cowl, therebyguarding against the formation of any space when the grate is moved to one side or the other of the division-wall to throw the heat into the room being used. The sides of the cowl are extended at an intermediate point at their lower ends, and are slotted, as shown at 9, to receive pins 10, projecting laterally from the extensions S, whereby the cowl is swung from the perpendicular upon moving the grate to one side or the other ofa normal position. The upper portion of the cowl is contracted and terminates in an approximately circular headv ll, which is cut away on its top side, as indicated at l2, izo-provide an escape for the products of combustion when the heater is performing service. The neck portion 13 between the head ll and the body of the cowl aifords clearance for the facings le above the fireplace and allows for the grate to be moved into one or the other of the rooms. The head portion engages with the walls of the flue or chimney and prevents the escape of heat, as clearly indicated in the drawings.

The vertical diaphragm 7 is pivotally supported at its upper end, as shown at l5, preferably in line with' the anis of the pivoted ,cowl 6, and normally occupies a vertical position, thereby admitting of the cowl swinging to one side or the other of the perpendicular without changing its position until engaged by a wall of the cowl, when the latter and the diaphragm move together, as will be readily understood, whereby the heat'is directed into one or the other of the rooms, or into each equally or proportionately, as required, by properly adjusting the heater with reference to the division-wall and rooms. Fire-boards 16 serve to close the open sides IOO or fronts of the fireplace, and when lowered into a horizontal position form protectors or metal hearths to prevent the burning of the iloor or floor covering when drawing the heater out into one or the other of the apartments. When the heater is drawn int-o one room, the open side of the fireplace leading into the other room is closed by the lire-board, and when it is required to heat both rooms alike the heater occupies a central position and both dre-boards are turned into a horizontal position. v

Having thus described the invention, what is claimed as new isl. In a grate for heating adjoining rooms, the combination with the movable heater, of a cowl pivoted at its upper end centrally above the heater and having positive connection at its lower end with the heater and movable therewith so as to be swung` from the perpendicular when moving the heater to one side or the other of a normal position, substantially as set forth.

2. In a grate for heating adjoining rooms, the combination of a movable heater, a cowl, pivoted at its upper end centrally above the heater and a pin-and-slot connection between the sides of the cowl at their lower ends and the sides of the heater, substantially as shown for the purpose set forth.

3. The combination with a movable heater, of a cowl pivoted at its upper end centrally above the heater and having its upper portion contracted, forming a neck for the purpose described, and having positive connection at its lower end with the heater to move there with, substantially as set forth.

4. The combination with a movable heater, of a cowl pivoted at its upper end centrally above the heater and having its upper portion contracted, forming a neck, and having an approximately circular head cut away on its top side, and having positive connection at its lower end with the heater to move therewith, substantially as set forth for the purpose described.

5. The combination with a movable heater, of a cowl pivoted at its upper end centrally above the heater and'having positive connection at its lower end with the heater to move therewith, and a pendent diaphragm located within the cowl, substantially in the manner set forth for the purpose described.

6. A heater for adjoining rooms, movable from a normal position into either, comprising a base mounted upon rolling supports and provided with a sectional grate or fire-basket, a cowl pivoted at its upper end centrally above the heater and having a pin-and-slot connection at its lower end between its sides and the sides of the base, and having an approximately circular head cut away on its top side and a neck portion between the head and body of the cowl, and a vertical diaphragm pendcntly supported within the cowl, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
